Summary

The main purpose of this study is to compare Hyperthermic Intraperitoneal Chemotherapy combined with Chemotherapy and Chemotherapy as a conversion therapy for gastric Cancer Patients with peritoneal metastasis in Safety and Effectiveness.

Detailed description

Follow-up results from the PHOENIX study failed to show statistical superiority of intraperitoneal paclitaxel plus systemic chemotherapy. However, in the subgroup analysis, it can be seen that after correcting for the bias effect of ascites, the difference between the two groups was statistically significant, further proving the significance of ascites control on the prognosis of patients with gastric cancer peritoneal metastasis. Based on the existing data, for patients with moderate amount of ascites, the IP regimen is recommended to control ascites and relieve ascites. Symptoms, purpose of improving quality of life and prolonging survival. HIPEC is traditionally used to treat peritoneal cancer. Patients who diagnosed with gastric cancer with peritoneal metastasis were divided into two groups based on whether they underwent HIPEC. The primary endpoint is the R0 resection rate and the secondary endpoints are 1-year overall survival, and Safety.

Conditions

• Gastric Cancer

Interventions

Type	Name	Description
PROCEDURE	Comparing Hyperthermic Intraperitoneal Chemotherapy	After laparoscopic exploration, HIPEC was started immediately: the temperature was 43 ℃ and the duration was 60 min. paclitaxel (PTX) was used with a dose of 50mg / m2. The second HIPEC was completed 24-48 hrs after the first HIPEC, and at least 4 HIPEC was completed.
DRUG	Paclitaxel	A natural anticancer drug that has been widely used in the treatment of breast, ovarian and some head and neck and lung cancers.Three to six weeks after HIPEC was completed, chemotherapy was started:: PTX: 50mg / m2 IV, D1, D8; PTX: 20mg / m2 IP, D1, D8; q3w; S-1: 60mg / m2, bid, d1-14, repeated every 3 weeks.
DRUG	S1	S-1 is an oral fluoropyrimidine consisting of tegafur (a prodrug that is converted to fluorouracil, mainly in liver microsomes but also in tumour tissue), gimeracil (an inhibitor of dihydropyrimidine dehydrogenase, which degrades 5-FU), and oteracil (which inhibits the phosphorylation of 5-FU in the gastrointestinal tract, thereby reducing the toxic effects of 5-FU in the intestinum).Three to six weeks after HIPEC was completed, chemotherapy was started:: PTX: 50mg / m2 IV, D1, D8; PTX: 20mg / m2 IP, D1, D8; q3w; S-1: 60mg / m2, bid, d1-14, repeated every 3 weeks.
